How to Set the Time on Your Guardian Alarm System – Learn how to easily set the time on your Guardian security system so that you can be sure your home is protected.


The Guardian alarm system allows you to set both an alarm and time on the device. The time is important for the alarm system to function properly, so it is important that it is set correctly. This article will provide instructions for how to set the time on your Guardian alarm system. We will look at the steps for setting the time and how to confirm that the time is set correctly.

What is a Guardian Alarm System

Guardian Alarm System is a comprehensive alarm system that provides extra protection and peace of mind to home and business owners. This system is designed with the ease-of-use of modern technology in mind and allows users to program custom settings, such as setting their own time, using only their keypad or an app. The Guardian Alarm System contains up to eight wired zones, each with an integrated motion detector, contact sensor, smoke detector or panic button. The system also includes a siren which the user can set to sound whenever a detected breach occurs. Its high level of security makes it an ideal choice for both residential and commercial properties.

Setting up and maintaining your Guardian Alarm System requires a few simple steps. When first setting up your system, you will need to program the time on each zone’s separate clock so that you know when alarms will sound throughout the day or night. A few easy adjustments using the keypad or an app can mean having accurate alarm time available at all times. You may also want to adjust settings such as Quiet Zones so that certain areas don’t sound alarms during times when you don’t want them too (e.g., during office hours). Additionally, there are other ways such as notifications via email and text message that allow you to keep track of your Guardian Alarm System remotely from any device connected to the internet.

Setting the Time

Setting the time on your Guardian Alarm System is relatively straightforward. The first step is to hold down the “Set” button on the panel until the time led flashes. Once you’ve done this, you can use the arrow keys to enter the current time. You can then press the “Set” button again to confirm the time and you’re done. Let’s take a look at a step by step guide to setting the time on your Guardian Alarm System.

Locate the Set Time Button

Once you have your new Guardian alarm system, it’s important to make sure the time on the system is correct. This will help you securely monitor your home and also ensure accurate recordings for any connected surveillance cameras. Setting the time is easy once you know where to look.

To begin, locate the panel keypad in your house and press and hold down the ‘Program’ button until ‘Installer Code’ appears on the display. Enter your code and press ‘Continue’. You will see the option to ‘Set Time’. Press this button now, then press ‘Set Time Now’.

The display should now show a list of 24 hour clocks with blanks underneath them. These are hour settings, starting with 12 midnight at one end of the list and 11:00 PM at the other end (the leading zero will not appear). With each clock slot selected, enter in its corresponding value via number keypad. For example – type ‘3’ for 3am, ‘8’ for 8am etc.

When you are done entering in all of your desired time slots, press ‘Continue’. You can now adjust any other settings as desired before saving them by pressing ‘Save’. Your new alarm system should now be set to accurately reflect local time!

Enter your 4-digit security code

In order to securely program and activate your Guardian Alarm System, you must enter your 4-digit security code. This is an important step in protecting your home and ensuring that only authorized users can access the system.

The Guardian Alarm System requires a minimum of four consecutive digits used to secure the system against unauthorized access. If entered incorrectly, the alarm will not recognize new settings or commands. When setting up your Guardian Alarm System for the first time, make sure you securely remember this code and keep it in a safe place where it cannot be accessed by anyone other than yourself.

Once your 4-digit security code is correctly entered, you will be able to proceed with programming time settings on your alarm system. It’s important to set the correct time as this helps when setting alarms and determining when certain programmed events should take place. Setting the correct time also ensures that issues such as Daylight Saving Time are handled properly when adjusting times for automatic broadcasts or alerts from the system.

Select the Time Format

The first step in setting the time on your Guardian alarm system is to select the preferred time format. Depending on your controller model, you will be able to select between 12-Hour or 24-Hour time format. If you don’t know which format to choose, it’s best to go with the default setting; most models use the 12-Hour time format as the default setting. It is important that you make a note of which format you have chosen and stick to it; using an incorrect or mixed format can interfere with the accuracy of your alarm system.

Once you have selected a time format, use the controller’s display menu to enter in nautical time (for 24-hour mode) or AM/PM time (for 12-hour mode). If necessary, consult your owner’s manual for further instructions on how to set the correct date and clock settings for your Guardian alarm system.

Enter the Current Time

Prior to arming or disarming your Guardian Alarm system, you need to Access the System and enter the correct date and time. Setting the time is an important step for ensuring that all scheduled settings, such as arming and disarming times and chime settings, are accurate. Accessing the System and entering or adjusting the date or time is a simple process that can be completed in just a few steps.

To adjust the current date and time of your Guardian Alarm System:
1. Press “Menu” (you will hear one long beep).
2. Enter your 4-digit Master code (you will hear two short beeps).
3. Use the arrow keys to scroll down to “Date & Time” (you will also hear two short beeps).
4. Push “Okay” (you will hear one long beep).
5. Choose either “Date” or “Time” by using the up/down arrow keys
6. Once you have selected either Date or Time use the +/- keys to Access the System and adjust the current setting
7 If adjusting Time, press “AM/PM” to toggle between 12 hour format
8 When complete, press “Exit” twice to return to standby mode


If you are having difficulty setting the time on your Guardian alarm system, you may need to troubleshoot the issue to determine what is causing the problem. This can range from incorrect settings of the time to a defective component on the alarm system itself. In this section, we will go through the steps to help you troubleshoot and identify where the issue is coming from.

Check the Battery

Before you begin, make sure the backup power is working properly by checking the battery. If the battery is not supplying proper power to the system, then it will not be able to be set. The backup power system should be able to keep your Guardian Alarm System up and running even if there is a power outage. To test the battery, access it from the control panel and see if a red led light is blinking indicating that it has adequate back-up charge. If other indicators such as low voltage or no power appear, then replace the battery immediately before proceeding with setting the time on your Guardian Alarm System.

Make Sure the System is Connected to Power

Before setting the time on your Guardian alarm system, double-check to make sure it is powered on. This includes both the system itself and the control panel that’s connected. The control panel needs to be connected to a power outlet or a backup battery power supply. If either of these are not working, then you won’t be able to set the time.

If you are plugged into an outlet, make sure it is live by plugging in and testing something else, like a light or a small electronic device. If it has no power, try another outlet and check the circuit breaker or fuse box if necessary. If one of these may be at issue, contact an electrician for assistance before proceeding with setting up your alarm system’s time settings.

Once powered on, ensure that all other components of your system are connected properly in accordance with installation instructions. Make sure any sensors and security cameras have been installed as specified by your particular version of this Guardian model. Additionally, many Guardian systems require connection to a cellular network or Wi-Fi router so it can have constant communication with other components of the system – this must also be taken into account before proceeding further with setup!
